Title: I volunteered!
Post by: CROSSBOLT on July 27, 2021, 01:22:39 PM
Next door neighbor has a Honda 100 cc motorbike that would not start. Based on his description I concluded the carb was stopped up with decomposed, phase separated ethanol gas.

I was correct. That was absolutely the nastiest mess I have seen to date! Gooey, brown, thick syrup and watery slime, plugged jets, glued shut float valve and unknown stopped up passages. Spray carb cleaner, wire sprigs from a wire brush, small wire brush to remove scale and persistence aided by podcasts got everything (I hope) cleaned up. Maybe this morning it will be back on the bike before it gets too hot.

Honda, or Keihin used captive "O" rings on this carb instead of gaskets! Float bowl and intake manifold joints have thes and really speed things up!

More later...

No pictures of this gooey, plugged up mess??? Nice to see pics of the bike, too!

Crossbolt do you remember the gooey carburetor pictures that were posted of the People 150 carburetor?  Sounds similar,  although I gave up and replaced the carburetor. 

Iahawk posted the pictures for me.

Finished product! Wanted to get a video of this thing starting and idling but he had all the gas drained out when I got back with the camera.

The first start sequence was full choke, switch off, three cranks of kick starter. Then switch on ant it fired once on first kick. Fired and ran on second  kick! Once warmed, choke off, it idled smoothly and slowly.

Owner very happy, happy!
